start-up enabling push-button (SW2) (which can be

used simultaneously with the brush levers) and the

solution ow switch (SW3).

The switch outputs controls the relevant outputs: re-

lay (K1) for brush motor, relay (K2) for vacuum sys-

tem motor, solenoid valve (EV).

The control circuit are protected by the fuse (F3).

The negative output of the battery charger (B2) al-

lows function activation when battery level is suf-

cient and the battery charger is not connected to the

electrical mains.

The LED electronic board (EB1) is equipped with 3

LEDs which indicate the battery charge level, both
